Study of elementary particles of astronomical origin.
Experiments let us learn about elementary particles and their interactions. More editors are needed here to add more experiments.
Neutrinos are some of the most difficult to observe elementary particles. They interact only weakly. Most of them escape without detection, only a tiny fraction of them can be seen. There are three kinds of neutrinos: electron neutrino, muon neutrino and tau neutrino. Neutrinos can oscillate i.e. they can change their identity in flight and transform from one kind of neutrino into another kind of neutrino. Sources of observed neutrinos include: nuclear reactors, accelerator beams, radioactive sources, secondary particles created by interaction of cosmic rays in the atmosphere, Sun, supernovae. Other possible sources are: dark matter, gamma ray bursts, active galactic nuclei, relic neutrinos, Earth interior.
Traditionally elementary particle research was done mostly with accelerators (fixed target and colliders). Other experiments have recently become more popular, especially as the largest (highest energy) accelerators became very expensive.
Scientists working in the field of particle physics.
Publications: print and electronic.
Institutions and sites with elementary particle experiments. Frequently centered around a large particle accelerator.
Software libraries and programs used by particle physicists.
